For power transformer of larger ratings, the tapping’s are located in the middle portion of the winding to
1
Increase the break-down strength of the winding insulation
2
Enable better cooling of the windings
3
Enable better distribution of inter-turn voltage
4
Reduce the mechanical force affecting the winding during short-circuits.
